Quote:What would have been the right handicap for this to be an even match? Minus the Q? Minus a Rook and pawn?

Many times the pawn in front of the removed rook is starts pushed, in this case it would start at A6, so durrr had a slightly bigger advantage than normal rook odds.

A queen feels like way too much, cuz even if durrr is inexperienced he's naturally intelligent enough to figure things out. I'd say 2 minor pieces. Usually in games like this rook odds is actually better, because the better player has one less minor piece to use and immediately rush to seize the initiative.
